Be it known that I JosHUA D. HOWELL, a residentot VForterville, inthe-county oil/Tulare and Sta-te ofCali'tornia, a citizen ot' the UnitedStates, have; invented certain new and useful Improvements inVVatclnnakcrs j `Tools, or" which the following is a specication. v Y

My invention relates tor improvements, .in watchmakers tools vvandret-ers particularly to a tool or implement employed inthe `sot--ting-or mounting of jewels, and the main object ot' my invention is theprovision ot a tool which will permit the workman to perl form theoperation of'jewel setting in a rapid and perfect manner, and thusprovide a highlyguseful, desirable and eiicient tool of this character.'A

Another object of my invention is the provision ot a tool ot thecharacter and-tor the purpose stated which will be otsmall size,

which can be easily supported upon the.

bench .and dispose 'the parts to be operated upon in the most desirableposition. which can beinstantly adjusted to the work, and which can bemanufactured at such a low price as to make its use practicallynecessary.

To attain the desired objects my invention consists of the jewel-settingtool herein shown, described and particularly detined and distinguishedby the claims, the right t0 make any changes which come within the'scope ot said claims being reserved.

In order that the construction in detail and the mannerV ot using mydevice may be understood and its many advantages be appreciated, Iinvite attentionlto the accompanying drawings, in which: A

F igure l represents a side eleifation ot v the complete tool forsetting jewels con--V structed according to my invention,

Fig. 2 represents a topplan view of the tool. Y

Fig. 3 represents a sectional view on the l5 line 3 3 of Fig. 2. 1

Fig. il is a Jfront or tace view of the clampinn` member or disc ot mydevice.-

Fig. 5 is a view on the line 5--5 of Fig. 3, and Fig. 6 is a sideelevation of the complete device showing the manner of operation anduse,

tion and consists of the 'handle or grasping portion l, which is madepreferably of wood The tool is of extremely simple construcor other heatnon-conducting material, and ot' the proper siZ'e and shape. havingmounted therein themetal-guiding sleeve' 2, which receives and guides"the tubular stem. 3, which carries at its inner end 'the holding orclamping head or disc 4, provided Vwith anl opening 5 toreceive theair-spring stud `carried by the usual-.balancenfheel (i, and

said disc` clamps the balance wheel against the-open orloop-shapedportion 7, oftheinclined disposed heat-conducting member',` 8, which issecured. rigidly .to the heating. head v9, forming a partofthe-supporting arm 10, Y

which rests'upon the bench 11, andis toi-ined with a band or collar 12,fitting upon the reduced inner end 13, of the handle orV graspingportion, this comprising the entire struc- .ture and showing the balancewheel in position to operate upon its jewel.'

From the foregoing description, taken in connection with the drawing,the operation or manner ot' using lmy 'invention will kbe readilyunderstood-and it will be noted that the device in operative positionassumes theY attitude shown in Fig. 6, withv the balance wheel inposition shown and this permits f theoperator to place one hand upon *hehandle and allows free operation of hisother hand in the operation otsetting` the jewel in the shellac, as is usual, and also permits thehead and heat-conductor to be thoroughly heated in the manner'desired,all ot which will be readily understood by the watchmaker or othersskilled in the art of jewel setting. j

It will be at' once apparent that I provide be operated on'where theyare freely accesf a small, compact, simple and inexpensive sible, whichcan be instantly adjusted to hold the parts in the desired position,which will properly receive and distribute theheat, and which in everyparticular will prove useful, desirable, practical and efficient.

A most important advantage is gained from the construction of my device,by reason Vof lthe Jfact that the tool is supported upon the bench at anincline. the handle having its outer end resting on the bench, the innerportion of thev heat-conducting portion also resting on the" bench,` and`the heat-receiving'head being supported above and away from the benchWhere it can be easily heated without danger of burning the bench or thehand of the user.

I claim: Y

l. A Watchmakers toolof .the character and for the purpose described,consisting of a handle or grasping portion adapted :to have its outerend` rest on the bench to support the tool inA an inclined position,aheat- Yreceiving and supporting portion connected to. the 'handle andconsisting .of a. band engaging the fhanuileand an integral dependingvertically,disposed arm, 'an adjustable holding means mounted on thehandle for securing theworli: between said handle and supportingportion, said `heat-rereiv-in-g und supporting portion consisting o'l'an arxn adapted to 'have its-inner portion rrest lon the tb'ench, a head`formed on the. outer lcud of saidarni to receive `the `fheat vandarranged above the benc`h,'and a` member connected Vat its outer end tosaid head projecting inward and having 'a transversely arranged loop'atthrough, a stern arranged in said opening Y with 'its outer :endprojecting `beyond said handle, a clamping headearried by the inner endof said stem, an arm secured to the handle, having a Aportionv to reston a support, and a lieadfrlisposed -at 1Lhe outer end of said arm, anda member 'havingv its ruiter end secured to sai-d I'head and having atits 'inner end a loop', the o'losed'portion o1?V which ieadl is arrangedparall'lel to ithe clamping and cooperating therewithV to support v'theWork. y
